MICHAEL \VATERS, OF NEW YORK, N Y.

STEAM-ENGINE GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 246,578, dated August30, 1881.

Application filed June .28, 1881. (No model.)

To all whom it may concern:

Be it known that I, MICHAEL \VATERS, of the city, county, and State ofNew York, have inventedcertain useful Improvementsin Steam- EngineGovernors, of which the following is a specification. 2

The object of this invention is to provide a more sensitive steam-enginegovernor, and one that will operate, when additional work is thrown onthe engine, to instantly open the valves for the admission of acorresponding head of steam into the steam-cylinder, so that the usualslacking down of the engine on such occasions shall be avoided, andeconomies in power or fuel and in time be thereby obtained.

The invention consists of two ball-governors, one of which'is driven bya belt from the engine-sl1aft,while the other is directly connected withthe valve lever or'rod connected with each other by gear-wheels andbelts that operate to magnify in one governor the motion ofthe other, sothat the device shall instantly respond to the slightest requirement formore or less steam in the cylinder, all of which will be hereinafter setforth.

Figure 1 is a front elevation of the device, with parts in position foropening steam-cylinder valve. Fig. 2 is a sectional plan of the same online a; 00, Fig. 1. Fig. 3 is a partly sectionalfront elevation of thesame, with parts in position for closing steam-cylinder valve. Fig. l isa plan of the arms on a portion of the device.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents that section or element of the governorwhich is designed to be located nearest to the crank-shaft of theengine, and which is driven by a belt directly from said shaft. Thiselement consists of an upright shaft, B, supported and moving insuitable bearings and standard B, and having fixedupon it, near its topand at right angles thereto, a pair of parallel arms, 0, whose ends arebent upward, as shown at a, to afford support for the levers D, that arepivoted therein,

as shown at b. The arms O are held together by short braces a a, thecentral one of which is perforated, as shown at a Fig. 4, to fit overthe shaft B, and said arms O are secured on said shaft B by keys or inany other convenient manner. The outer ends of the levers D areweighted, as shown at c, to counterbalance the sleeve E, that encirclesand slides upon the shaft B, about the middle portion thereof; and saidlevers D have their inward-projectin g ends pivoted to verticalconnectin g-rods D, that extend down on opposite sides of the shaft B,and have their lower ends hinged, as shown at (I, to said sleeve E. Bypassing down between the arms 0 the rods D are restrained from torsionalor lateral motion, and the said sleeve E is designed to have alongitudinal keyway formed in it to receive the splinef of the shaft B,so that said sleeve E will not turn independently of shaft B. Encirclingthe top of the shaft B, near its top bearing, B, is a'fixed collar, F,in the opposite lugs of which are pivoted the arms F,

' carrying on their outer ends the balls F Said arms I are connectedwith the levers 1) by connecting-links F whereby the rising and fallingmotion of the balls F is communicated through said levers D andconnecting-rods D to the sleeve E.

On the sleeve E, about itslower end, is firmly secured a frictionbevel-wheel, G, whose function will be hereinafter set forth, and belowthe sleeve E a bevel cog-wheel, H, is firmly secured'on the s'haft'B,which cog-wheel H t gearswithacorrespondingcog-wheel,H,which is fixed onthe end-of a horizontal shaft, I, that is journaled in suitable'boxemy,and has keyed on it two pulleys, I 1 over the former of which runs thecrank-shaft belt K, that operates the device, while from the pulley I abelt, K, extends over the pulley S on the horizontal shaft S, that formspart of the governor section or element L, which is designed to'belocated nearest the engine-cylinder. This governor section or element Lconsists of an upright shaft, M, supported and revolving in suitablebearings and standard, M. Encircling the top of this shaft M is a fixedcollar, N, in the opposite lugs of which are pivoted thearms N, carryingon their outer ends balls N and to stiffen said arms N, to prevent theirtorsion and to limit their upward movement, a laterally-slotted segment,N is secured to the col-' lar N.

Pivoted to the arms N are the connectinglinks 0, whose lower ends arehinged to the sliding sleeve 0, on which is fixed the frictionbevel-wheel 0 that gears with the bevel friction-wheel Q on the shaft S,and below the sleeve and wheel 0 O a bevel cog-wheel, P, is firmlysecured on the shaft M, the function of which cog-wheel P will behereinafter set forth.

Supported in standards R is the horizontal shaft R, by which the twogovernor sections or elements are connected, and on one end of thisshaft R is keyed a bevel friction-wheel, T, with which at certain times,as hereinafter set forth, the bevel friction-wheel G engages to revolvesaid shaft It, while on the opposite end of this shaft R is secured abevel cog-wheel, T, that is designed to engage at certain times with thebevel cog-wheel P.

Pivoted on a suitable standard, U, is the valve lever or rod V, whoseforked end embraces the sliding sleeve O, as shown at m, while itsopposite end is designed to be connected with the engine-valve. (Notshown.)

\Vhen the engine begins to run the balls F N are down, as shown in Fig.Both elements then instantly start in motion, the belt K revolving theshaftI, which in turn gives motion to the section A through thecog-wheels H H, and the belt K giving motion to the shaft S, which inturn imparts motion to the section L through the friction bevel -wheelsQ In consequence of this motion the balls F? rise first and giveincreased motion to the section L through the medium of the shaft R, theelevation of the balls F pulling up the sleeve E and its attached bevelfriction-wheel Gr until the latter is in gear with the correspondingbevel friction-wheel T on the end of the said shaft B, and the cog-wheelT on the opposite end of the shaft R (which wheel T is designed tocontain a few more teeth than the corresponding cog-wheel, P) beingthereby made to revolve in gear with said cog-wheel P. This increasedspeedof the section L causes the ballsN instantly to rise somewhat andmeasurably to lift the sleeve and wheel 0 O and thereby the yoked end ofthe valve lever or rod V, whereby the opposite end of said lever or rodV is depressed thereby, in like degree closing the valve (not shown) andcutting off in equal measure the admission of steam into theengine-cylinder. (Not shown.) WVhen the engine is running withoutlaboring the sleeves on both parts of the governor always rise and falla little and very quickly, thus letting but little steam into thecylinder. When the engine begins to labor a little the sleeve E dropsfirst, throwing the friction-wheels G T out of engagement, which causesthe sleeve on part L to drop quickly, thus letting on steam until itincreases the motion of the engine and raises the sleeve E, whichcarries thefriction-wheel Gr upward to engage the friction-wheel '1,thereby giving increased motion and raising the sleeve on part L, sothat steam is shut off and let on quickly. When the engine begins tolabor heavily the sleeve E drops, thus causing the sleeve on part L todrop down quickly, fully opening the valve and letting a full head ofsteam into the cylinder, and continuing to do so until the engine ceaseslaboring heavily. The sleeve on part L never stops fully up nor half-waydown, but rises and falls quickly, except when the engine is laboringheavily, when it stays fully down until the engine stops laboringheavily. Both parts of the governor are always in motion when running ata high rate of speed.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. An improved steam-engine governor,constructed substantially as herein shown and described, consisting oftwo ball governor sections connected with each other by means of belt,sliding and fixed friction-wheels, shafts, and gear-wheels, arranged andoperating to transmitthe motion of one section to the other, as setforth.
